  • each platform 1 comprises a supporting structure constituted by two twinned box girders 2 and 2' separated by a gap 3 of which the width is substantially equivalent to the width of the girders, with the result that the width of each platform is divided into three equal thirds.
  • Each platform is preferably much longer than large, the ratio between the length and the width preferably being greater than 10.
  • Each platform is provided to receive a row of plurality of aligned, retractable seats, as will be seen in detail hereinafter, the seats are preferably disposed inside at least one of the box girders.
  • each platform thus corresponds to the width of a row of seats, increased by the space necessary between two rows of seats to allow passage and comfort of the audience or participants.
  • each platform is provided to receive at least one row of about twenty seats which are capable of being manoeuvred either separately or together, the whole row being displaced from its retracted position inside one of the box girders, towards an extended position as shown in FIG. 8.
  • the basic structure of the platform constituted by the two box girders 2 and 2' is completed by bracing elements common to the whole of the platform and connecting the two box girders 2, 2'.
  • these braces 4, 4', 5, 5' may be disposed at the ends and at intermediate positions along the length of the platform, as shown in FIGS. 1, 2 and 3.
  • Each box girder 2, 2' is preferably constituted by a U-shaped metal sheet and also includes inner stiffener frames 6, 6', 7, 7' oriented perpendicular to the longitudinal axis of the box girders 2, 2' and fastened within the box girders along the length of the box girders which define therebetween modular housings 8, 8', 9, 9', each receiving a retractable seat 10, 10'.
  • the two box girders 2, 2' are joined in their upper part, at the level of the gap 3, by a plate 10 supporting the rectangular horizontal panel 11 disposed between the two box girders 2, 2' which may constitute the floor of the platform between adjacent rows of seats.
  • each box girder 2, 2' On the upper part of each box girder 2, 2', overlying the housings 8, 8', 9, 9' used for receiving the seats in retracted position, there is disposed a covering plate 12, 12' covered with a surfacing or flooring 13, 13' which comes level with the rectangular horizontal panel 11 which is disposed between the two box girders 2, 2'. As shown in FIG. 8, the covering plates 12, 12' are mounted to pivot about pivot pins 14, 14'.
  • FIG. 5 in particular shows that, with the covers 12, 12' in closed position, the platform 1 offers on its upper surface a totally clear bare floor (the platform being able to provide this type of surface either when in high position or in low position).
  • the platform is mounted to move between a high position shown in FIG. 1 and the low position resting on the ground 15 as shown in FIG. 3, FIG. 2 showing the movement (in the direction of the arrows) and illustrating the lowering of the platform from its high position towards its low position.
  • the mechanical means used to produce the vertical displacement of the platform is preferably constituted by two extensible leg elements performing the function of extensible and retractable jacks; these two extensible leg elements 16 and 16' are each associated with a tie-rod 17, 17'.
  • the extensible leg element 16, 16' is constituted by two elements; an upper element 18 which is pivotally attached at its upper end about an axis 19 between the two box girders 2 and 2' and a telescoping lower element 20 is mounted for telescopic slide.
  • the tie-rod 17, 17' which might be constituted by a unitary element is, in the present embodiment, constituted by two twinned pairs of rigid elements.
  • metal tubes of quadrangular section 21, 21', 22, 22', respectively, disposed in pairs respectively on either side of the extensible leg element 16 may serve as the tie-rod 17, 17'.
  • the tie-rod 17, 17' (constituted by the four elements 21, 21', 22, 22') is articulated under the two box girders 2, 2' about pivot pin 23.
  • the lower end of the lower element 20 of the extensible leg element 16 and the lower end of the tie-rod 17 are furthermore joined at their base by a common pivot pin 29.
  • the two pairs 21, 21' and 22, 22', respectively of the elements constituting the tie-rod are pivotally mounted on two sliding shoes 24 and 24', these shoes being adapted to smoothly move within slideways or rails 25, 25', resting on the ground 15.
  • each pair and 22, 22', respectively, of the elements used of form the tie-rod 17, 17' is associated with a stabilizer 26, 26', itself pivotally mounted on one side to a fixed base 27, 27' and articulated pivotally mounted at 28, 28' at its opposite end substantially at the centre of the tie-rod 17, 17' the stabilizer 26 having a length equivalent to about half that of the tie-rod 17, 17' with the result that the stablilizer 26, 26' forms with the lower half of the tie-rod 17, 17' a isosceles triangle of which the articulation 28, 28' occupies the apex.
  • This relationship between the stabilizers 26, 26' and the lower halves of the tie-rods 17, 17' remains constant even when the sliding shoes 24, 24' move.
  • sliding shoes 24, 24' will preferably be provided with outer faces made of materials having a low coefficient of friction, and furthermore the exposed surfaces of the rails 25, 25' within which the sliding shoes 24, 24' will preferably, likewise be provided with coatings for smooth having a low coefficient of friction clearly, however, this system may be replaced by an assembly provided with rollers or rolling means likewise guided in a corresponding rail system.
  • the extensible leg elements 16 and 16', the tie-rods formed by the members of sections 21, 21' and 22, 22', as well as the stabilizers 26, 26', and the rails or slideways 25, 25', are all parallel to one another and are all disposed along the longitudinal axis of the platform.
  • the mechanical means for vertically displacing the platform is preferably constituted by a single motor 30 disposed substantially at the centre of the platform and in the inner gap 3 separating the two box girders 2, 2'; this motor 30 is associated with a reduction gear 31.
  • a pair of colinear shafts 32, 32' on either side are disposed and are disposed in diametrically opposite directions of the reduction gear 31.
  • FIGS. 6 and 7 in particular show that the shaft 32 preferably terminates at and is connected to a Universal joint 33 having an axis (crosswise) which is colinear with the axis 19 defined by the attachment of the upper end of the upper element 18 of the extensible leg element 16 and the two box girders 2, 2'.
  • the Universal joint 33 allows transmission of the movement from the shaft 32 to the rotational threaded rod 34 which is mounted to rotate inside the telescopic element 18 of the extensible leg element 16.
  • the threaded rod 34 is mounted to rotate without being able to move longitudinally, being immobilized by the set of bearings formed by opposite thrust ball bearings 35.
  • the threaded rod 34 is inserted in a bronze block 36 help immobile within the upper end of the lower telescopic element 20 of the extensible leg element 16, the bronze block 36 constituting a captive nut driven in longitudinal displacement along threaded rod 34 by the rotation of the threaded rod 34.
  • the drive of the two extensible leg elements 16, 16', by a common motor ensures in original and particularly efficient manner, the perfect synchronism of the actuation of the two right and left extensible leg elements 16 and 16' respectively, consequently ensuring the raising or lowering movement of the platform, and furthermore ensuring that the platform 1 will remain constantly horizontal and parallel to the ground during this raising and lowering.
  • FIG. 2 shows that, as a function of the retraction (or, inversely, of the extension during the opposite movement) of the extensible leg elements 16', the sliding shoes 24, 24' held captive inside the guide rails 25, 25' move in a centrifugal direction towards the ends of the guide rails 25, 25', as the platform assembly lowers.
  • the platform assembly In low position, as shown in FIGS. 3 and 5, the platform assembly rests on the ground via lower sections 37, 37', 38, 38', respectively, disposed parallel to the length of, and beneath each of the box girders 2, 2'.
  • each end of, the lower sections 37, 37', 38, 38' is bevelled, thereby allowing for the insertion of the sliding shoes 24, 24' within the guide rails 25, 25', the platform in totally lowered position.
  • the lower sections 37, 37', 38, 38' transfer, in places and in homogeneous and regularly distributed manner, the forces likely to be received in the event of considerable loads being applied on the platform in low position.
  • the sections 37, 37', 38, 38' rest on the ground 15 either directly or, as in the embodiments described here, as best seen in FIGS. 2 and 3, via rails 25, 25'.
  • the rails 25, 25' having a length corresponding to the useful stroke of the sliding shoes 24, 24', might be embedded in the ground 15.
  • these rails 25, 25' may be elevated, whilst resting on the ground; in that case, the rails are extended, outside their active part, by support elements extending the rails and adapted to receive, in their position of rest, sections 37, 37', 38, 38'.
  • each of the box girders 2, 2', having disposed therein the housings 8, 8', 9, 9' preferably receives a plurality of seats 40, each seat being constituted by a module adapted to be displaced in height between a retracted position inside the housing (within the box girder) and the high extended position as shown in the left-hand part of FIG. 8.
  • the platform thus comprises two rows of seats disposed respectively in one and the other of the two box girders, the seats being disposed face to face; whereby it is thus possible to place one row of seats or the other in active position, thus making it possible to use the hall in multiple ways, the centre of interest thus lying at one end or at another; in either case the seats may be placed in active position so as to face the event.
  • the hall may be used in one direction or in another.
  • each module constituting a unitary seat 40 capable of being extended vertically from its housing, 8, 8', 9, 9' is itself constituted by an assembly in which the seat 42 and the backrest 43 are connected together about a common horizontal hinge 44 located at the base of the backrest 43.
  • the seat 42 is itself mounted to pivot about a horizontal pivot pin 45, which connects the two lateral armrests 46 (forming part of the displaceable module).
  • the backrest 43 is itself connected on each side to each of the lateral armrests 46 by a connecting rod 47 connected, on the one hand, at 48 to the armrest and at 49 to the backrest 43.
  • the pivoting of the seat 42 about the horizontal pivot pin 45 brings about the opening/closure movement of the chair 40 by angular approach of the seat 42 and the backrest 43, whilst the connecting rod 47 automatically controls tipping of the whole seat 40 towards a vertical, compact position, the two elements (i.e., the seat 42 and backrest 43) being returned against each other when in the retracted position inside the housing 8, 8', 9, 9' constituted within the box girder 2, 2'.
  • all of the motorization means constituted in particular by motor 30 equipping each of the platforms, as well as the motors (not shown) controlling the movement of elevation and retraction of the seats 40 may be connected in conventional manner by electrical circuits to a central station, from which the movement of elevation or of lowering of each platform and the movement of elevation or of positioning of each seat 40 or each row of seats, may be remotely controlled.
  • Modifications may then be made very rapidly by simple remote-control for individually actuating each platform to the desired height and automatically stabilized the platform 1 in its position, each platform remaining parallel to the ground 15 and stable in any position, its positioning in space being controlled in stable manner by the stabilizers 26, 26' which each have one anchored to the ground.
  • Tiers may therefore be formed (as shown in FIG. 9), in any geometrical configuration or angle, allowing in particular two halves of the hall to face each other mutually, the audience looking towards the centre, or, on the contrary, the whole of the hall facing a spectacle taking place on one side or the other.
  • Another variant embodiment may also be made in which the rows of seats 40, are extended through an openable face of one or both box girders 2, 2', the rows of seats then being brought, after extension from a platform, above the adjacent platform brought to a lower level so that the horizontal panel of this adjacent platform comes at the level of extension of the row of seats.
